PCB inoreva bhodhi redunhu rakadhindwa, rinova mupi wekubatanidza magetsi ezvikamu zvemagetsi.Iyo yakajairika muindasitiri yemagetsi, uye iyo conformal coating inoshandiswawo zvakanyanya.Iko hakuna kunamatira kwePCB matatu proofing glue (pendi).Muchokwadi, ndeye kushandisa dhizaini yeyakaomeswa coating paPCB.
Conformal coating materials ndeyekudzivirira PCB kuti isakuvadzwe nezvinhu zvekunze uye kugadzirisa hupenyu hwesevhisi yePCB.Sezvo zvigadzirwa zvemagetsi zvemhando yepamusoro zvine zvakakwirira uye zvakakwirira zvinodiwa zvePCB mhando, pendi yependi mitatu inoshandiswa zvakanyanya pamabhodhi edunhu.
Zvinhu zvinogona kukonzera PCB kukuvara:
Kunyorova ndicho chinhu chakajairika uye chinoparadza kuPCB.Kunyanya kunyorova kunoderedza zvakanyanya kudzivirira kwekudzivirira pakati pemakondakita, kukurumidza kuora, kuderedza Q kukosha, uye corrode conductors.Zvinowanzoitika kuti chikamu chesimbi chePCB chine mhangura yegirini, iyo inokonzerwa nekemikari yemhangura yesimbi ine mhute yemvura uye oksijeni.
Mazana ezvinosvibisa anowanikwa zvakasununguka pamapuranga edunhu akadhindwa ane simba rakafanana rekuparadza.Vanogona kutungamirira kumigumisiro yakafanana nekukukurwa kwehunyoro, zvakadai sekuora kwemagetsi, kuora kwema conductors uye kunyange pfupi pfupi.Izvo zvinosvibisa zvinowanzowanikwa mumagetsi emagetsi zvinogona kunge zviri zvinhu zvemakemikari zvakasara mukugadzirisa.Izvi zvinosvibisa zvinosanganisira flux, solvent release agent, metal particles uye inki yekumaka.
Kune zvakare mapoka makuru ekusvibisa anokonzereswa nemaoko evanhu, akaita segirizi revanhu, mafingerprints, cosmetics uye zvisaririra zvekudya.Kune zvakare zvakawanda zvinosvibisa munzvimbo yekushanda, zvakaita semunyu wekupfapfaidza, jecha, mafuta, asidhi, imwe mhunga inoparadza uye mold.
Sei uchiisa glue katatu (pendi)?
Iyo PCB yakashongedzwa neyakaomeswa yekupfekedza zvinhu haingogone kuve hunyoro-hupupuriro, guruva-hupupu uye kusapinda mvura, asi zvakare ine zvimiro zvekutonhora nekupisa kuvhunduka, kuramba kuchembera, kusamira kwemwaranzi, mhute yemunyu kuramba, ozone corrosion resistance, vibration resistance, kuchinjika kwakanaka uye kunamatira kwakasimba.Kana ichinge yakanganiswa nezvinhu zvakashata zvenzvimbo yekushanda, inogona kuderedza kana kubvisa kuderera kwekushanda kwemagetsi.
Nekuda kwenzvimbo dzakasiyana dzekushandisa dzezvakasiyana zvigadzirwa zvekupedzisira, zvinodikanwa zvekuita zvehutatu hwekunamira hunozosimbiswa.Midziyo yemumba yakaita sefiriji, muchina wekugezesa uye mahita emvura ane zvinodikanwa zvakakwirira zvekudzivirira hunyoro, nepo mafeni ekunze nemarambi emumugwagwa anoda yakanakisa anti fog performance.
Maitiro ekukurumidza uye nemazvo kushandisaconformal coatingkuPCB?
Muindasitiri yekugadzira PCB, mune otomatiki michina yakatsaurirwa kuvhara pendi yekudzivirira yemapuranga edunhu -conformal coating muchina, inozivikanwawo sematatu ehumbowo pendi yekupotera muchina, matatu ehuchapupu pendi yekupfapfaidza muchina, matatu ehuchapupu pendi yekupfapfaidza. muchina, zvichingodaro, wakatsaurirwa kudzora mvura uye kufukidza chidimbu chetatu cheuchapupu pendi pamusoro pePCB, sekuvhara dhizaini yephotoresist pamusoro pePCB nekupfekera, kupfapfaidza kana kuruka coating.
Iyo conformal yekuputira muchina unonyanya kushandiswa kupfapfaidza chaiyo, kupeta uye kudonha kweglue, pendi uye zvimwe zvinwiwa mukugadzirwa kwechigadzirwa kunzvimbo chaiyo yechigadzirwa chimwe nechimwe.Inogona kushandiswa kudhirowa mitsetse, madenderedzwa kana maarcs.
Conformal coating muchina mudziyo wekupfapfaidza wakagadzirirwa kupfapfaidza pendi yehumbowo hutatu.Pamusana pezvinhu zvakasiyana-siyana zvinofanirwa kupfapfaidzwa uye iyo inoshandiswa kupfapfaidza mvura, kusarudzwa kwechikamu chemushini wekuputira muhutano hwemichina yakasiyanawo.Iwo matatu anti pendi yekuputira muchina anotora yazvino kombiyuta yekudzora chirongwa, iyo inogona kuona matatu-axis yekubatanidza.Panguva imwecheteyo, yakashongedzerwa nekamera yekumisikidza uye yekutevera system, iyo inogona kunyatso kudzora nzvimbo yekupfapfaidza.
